I currently do business with another component vendor (I won't name it here) and I'm seriously considering ditching them. For reasons that are beyond my understanding they believe it's good design to hide exceptions thrown within their components event handlers:

Try
    RaiseControlEventMethod()
Catch ex As Exception
    'Do nothing
End Try


I'm interested in Telerik's controls but first I want to know if I'll come across such horrible design principles again.

Any input would be very much appreciated. Thanks.

Hi,

Some of the telerik controls doesn't get grayed out (doesn't look disabled) even when it is disabled.
The controls still appears enabled with black color border for RadTextboxes ,radio buttons, checkboxes and combo boxes.
This issue exits in IE and is not found in Mozilla and Chrome.
Kindly help me out.

Thanks in advance,

Hello All,

I am facing an issue in RadnumericTextbox.
When i disable it through jquery(the below code) it looks disabled but the textbox is still editable.
RadnumericTextBox.set_enabled(false);
On making it readonly and then again enabling it, makes the spin buttons disabled.
Is this an issue with the telerik control?
Kindly help me out.

Thanks in advance,
Andrey

I am building an app that uses Windows 8 Metro XAML preview controls. I have downloaded and examined the sample app, but it mostly uses code-behind to define all the stuff necessary for the charts. I am trying to accomplish something similar with bindings, and the charts remain empty. Actually, they get the data, but plot nothing (for example, I can see the borderline of the RadPieChart and all zeroes for RadCartesianChart). Here is the code for RadPieChart:

<telerik:RadPieChart>
    <telerik:PieSeries ItemsSource="{Binding AssetsData}" />
</telerik:RadPieChart>

And AssetsData is defined like this:

private ElementCollection<PieDataPoint> assetsData;

public ElementCollection<PieDataPoint> AssetsData
    {
        get
        {
            return assetsData;
        }
        set
        {
            assetsData = value;
            Notify("AssetsData");
        }
    }

Filled with data, like this:
PieSeries series = new PieSeries();
series.RadiusFactor = 0.9;
  
foreach (var entry in dataSource)
{
    series.DataPoints.Add(new PieDataPoint() { Value = entry.Percentage, Label = entry.Title });
}
  
assetsData = series.DataPoints;

Everything works fine when I use code-behind (C#) like in the sample app. I define the series, add the datapoints to series and add that series to chart control. When using the same data and trying to bind like this, it doesn't work.

What am I doing wrong here?
I checked if the values in the collection are set properly, and they are (since I'm using the same logic as when I use code-behind, there shouldn't be any difference really, and there isn't).

Also, is there a way to set RadCartesianChart to scale it's minimum and maximum according to the data that's being drawn?

Hi ! I already have my blog where I've posted few asp.net examples and stuff like that. I also wanted to do the same for telerik. Any precautions should I take before I do so ? Do we have to own the telerik controls for doing so, or one can freely share the codes ?

I am expecting the ans in the capacity of an employee.

Thanks much.

We are using telerik RAD editor in our application to edit and manage the content. The content in our application contains huge amount of data which includes table, charts, graphs etc.

The controls that contains large tabled hangs when they are clicked. This happens only with IE 9 browser and the functionality works absolutely fine in other browsers.

Please suggest how we can fix this issue as large tables are part of our content.

I am trying to add Telerik’s controls (like RadMaskedTextBox, RadNumericTextBox and RadDateInput controls) dynamically into a user control (under the Page_Init event) which is itself a child of another user control.

 

When I run the project, following exception occurred and nothing is shown in the user control.

“Microsoft JScript runtime error: Sys.ArgumentException: Value must not be null for Controls and Behaviors. Parameter name: element”

 

However, these controls are added directly on a .aspx page without any exception and it appeared that the Telerik’s controls get registered in the Page_PreRenderComplete event of an .aspx page and since this event does not exist in a user control therefore they are throwing the above exception.

Hi!

I am in charge of implementing one (or more than one) mobile test automation solution in my company. My requirements:
- test mobile sites on real devices or iOS simulator via xCode (using Safari);
- test iOS native apps on real devices or iOS simulator;
- test Android native apps, again on real devices or simulators.

Can any of Telerik solutions help me implementing it? Do you know any other solutions then I can use in one of this cases? Thanks!
